tension and eliminating direct compression thus rendering the tire exceedingly serviceale and providing the desired cushioning e ect.

In order to accomplish the desired result, use is made of a resilient body in the form of a hollow rubber annulus adapted to bei fastened to the felly of the wheel, a floating metal rim attached to the peripheral face of the said resilient body, and a rubber tread attached to the said Boating metal rim.

A practical embodiment of the invention is re resented in the accompanying drawings orming a part of this specification, in which similar characters of reference indicate corresponding dparts in both views.

Figure 1 is a si e elevation of a portion of a resilient vehicle tire as applied and with parts shown in. section' and Fig. `2 is an enlarged cross section of the saine on the line 2-2 of Fig. 1.

The body 10 of "the vehicle tire is in the form of an annulus of rubber or a similar resilient material. The body 1D is approximately rectangular in cross section and its opening 11 is Ivlreferablyf made oval in cross section with t e ma'or axis disposed in a vertical plane, as in icated in Fig 2. The body 10 1s reinforced adjacent its outer peripheral face by layers 12 of fabric mate rial, and similar fabric la ers 13 are arranged adjacent the inner acc of the bod 10. The side walls of the body 10 are pre erably made in layers 14 disconnected from each other at the middle portion of the body to render the body 10 vexceedingly fiexible in a lateral direction and to prevent overheat ing of the body.

The inner face of the body 10 fits on the peripheral face of the felly 15 and the body 10 is secured thereto by bolts 16 extending s radially through the felly 15 and screwing into threaded bosses 17 projecting inwardly @rom a. hollow ring 18 embedded 1n the body' 10 intermediate the inner face andtliebottom of the opening l1. A washer y19 isi-iw A eted on the boss 17 and embedded in the'in'. ner face of the body 10. lBy ment described the body 1071s securelyfas tened to the elly 15 along the'median `fenter line of the bod and the fellyythus allow- -ing free flexing o the body 10 in a sidewise I is embedded in the body 10 intermediate the,

the anfange- ,so

top of the opening 1l and the middle por- 75 tion of the peripheral face of the body 10, and by this arrangement sidewise flexing of the body 10 is not interfered with. It will also be noticed that the ring 24 provides a' firm support for the floating rim 20 rand pre 80 vents accidental bending thereof, The tread 2l is vulcanized or otherwise attached 'to the fioating rim 2OP and is provided with open ings 25 in register with the screws 22 to per? mit of screwing the latter into the bosses 23 or unscrewing the same therefrom. wlienever it is desired to fasten the rim and tread in place on the body 10 or to remove them therefrom. The o enings .25 are nominallyi filled with rubber p ugs 26 to render thepe- 9o ripheral face of the tread of unbroken com tinuity. The rubber plugs 26 are preferably made conical to prevent the same from accidentall becoming detached from the tread 21, an the plugs 26 also serve to hold the screws 22 from accidentally screwing out of the bosses 23. A. washer 27 is riveted on cach boss 23 and is embedded in the peripheral face of the body 10 and is in contact with the floating rim 20. The washers 19 and 27 reinforce the body 10 at the holes engaged by the bosses 17 and 23.

`It is understood that the resilient side walls of the body 10, coming at the top of a wheel when the tire is fastened thereto, are stretched or extended under the load or radial strain; the side walls coming at the sides of the wheel are extended; and those at the bottom of the wheel are flexed downward and oetward. Thus direct com ression, such as is found in solid tires, is e iminated, it being understood that rubber is rim.

more elastic on iiexion or extension than en direct com ression.

The res ent `vehicle tire is exceedingly simple in construction and composed of comparatively few arts not liable to et out of order, and the ody is constructs to practically eliminate direct compression and to substitute flexion and extension.

Having thus described my invention, I claim as new and desire to secure by Letters Patent :-b
